The relation between the interception factor and signal parameters is deduced. Large time bandwidth (TB) product is a necessary condition for an LPI signal.

导出了信号截获因子与信号参数的关系，认为大的时间带宽积是低截获概率信号的必要条件。

LFM (Linear Frequency Modulation) pulse is a kind of important large time-bandwidth product signal and commonly used in modern radar system.

线性调频脉冲是现代雷达系统中常用的一种重要的大时宽-带宽积信号。

Because of the LPI radar's large time-bandwidth product, UWB radar has a high processing gain to cancel the advantage of the intelligence receiver at intercept range.

由于LPI雷达具有大时间带宽积，故超宽带雷达具有高处理增益而抵消侦察接收机在侦察距离上的优势。
